experimental: add fdl (Full Data Logging) translator
NSR needs logging that is different than our existing changelog in several ways: * Full data, not just metadata * Pre-op, not post-op * High performance * Supports the concept of time-bounded "terms" Others (for example EC) might need the same thing. This patch adds such a translator. It also adds code to dump the resulting journals, and to replay them using syncops, plus (very rudimentary) tests for all of the above.
